A further object of the invention is to provide means for releasingsteam through a jet at or near the bottom of storage tanks.

A further object is to provide a shield encasing a. steam line so thatthe same is completely covered where the same passes through the fueloil or petroleum in order that the fuel oil or petroleum may not come incontact with the heated steam line.

A still further object is to provide means for holding the steam linecentrally within said casing.

It is common knowledge that storage tanks containing fuel oil andpetroleum collect bottom sediment. This bottom sediment consists of amixture of water, dirt, and other foreign substances together with thefuel oil or petroleum. It is also common knowledge that the longer thesestorage tanks stand the greater the necessity for the use of means forseparating the fuel oil or petroleum from this bottom sediment.

In the heating of fuel oil or petroleum it has been the common practiceto use certain chemicals in connection with the heating in order thatthe film sacks may be broken down releasing the fuel oil or petroleumand separating foreign substances and Water that may be held Withinthese film sacks formed in the bottom sediment in the tanks.

It is not the purpose of this invention to claim any particular chemicalbut to describe and claim a device for inexpensively and effectivelyseparating this bottom sediment in order that water, dirt, and otherforeign substances may be efliciently separated from the fuel oil orpetroleum.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a vertical view of the device installed Within a tank.

Figure 2 is an enlarged detail view of Figure 1 showing the device withparts broken away.

By referring to the drawing it will be seen that there is provided atank 1. This tank 1 contains fuel oils or petroleum. The device consistsof a steam line 3 which is inclosed by a casing 4. An upper end 5 of thecasing 4 is provided with a support web 6 for the purpose of holding thesteam line 3 centrally within the casing 4. It will be seen that a lowerend 7 of the casing 4 is provided with a sealed end 8 in order that nofuel oil or petroleum or water may get within an air chamber 9 formedbetween the steam line 3 and the interior of the casing.

It is important to prevent the oil from coming 79 in contact with thesteam line 3. If the oil or petroleum is subjected to a relatively highdegree of heat the same becomes discolored and starts to evaporate. Thisdiscoloring of the oil is ob jectionable in that the quality and gradeof the oil is changed so that the same is not worth as much in thefinished product. It is also desirable to prevent evaporation becausethis evaporation constitutes a total loss. By the use of the casing 4covering the steam line 3, where the same 80 passes through the tankcontaining oil, a greater degree of heat is used and the process ofreclaiming the oil is carried on with greater speed without the loss byevaporation and discoloration. A lower end 10 of the steam line 3 isprovided with an elbow 11 which carries a steam jet 12.

In operating the device water is put into the tank 1 until the contentsof the tank 1 is carried by the water above the lower end 7 of thecasing 4. This is done in order that no fuel oil or petroleum will comedirectly in contact with the steam line 3.

It is understood that a plurality of these devices may be placed withina tank depending upon the size of the tank and the amount and thicknessof 5 the sediment within the tank.

What I claim is:

1. In an oil reclaiming device, the combination of a storage tank forcontaining fuel oil or petroleum, together with a steam line extendingdownwardly into said tank, a casing inclosing the major upper portion ofsaid steam line, a support web positioned on said steam line at upperend of said steam line and casing, an air chamber formed between saidsteam line and interior of said casing, a closed lower end of saidcasing, a steam jet positioned at extreme lower end of said steam lineand below said casing.

2. In an oil reclaiming device, the combination of a storage tank forcontaining fuel oil or petroleum, together with a plurality of steamlines extending downwardly into said tank, a casing inclosing the majorupper portion of each steam line, a support web positioned on each steamline at upper end of said steam line and easing, an air chamber formedbetween said steam lines and interior of said casing, a closed lower endof said casings, a steam jet positioned at extreme lower end of eachsteam line and below said casing.

3. In an oil reclaiming device, the combination of a storage tank forcontaining fuel oil or petroleum, together with a plurality of steamlines ex-
